the monitoring and controlling of environmental pollutions are very important in biological and industrial processes, and a great interest is growing with the development of suitable gas–sensitive materials and hazardous chemical removal devices. in this work, the highly parameterized, empirical exchange–correlation functional m06–2x were employed to investigate the electronic sensitivity of pe...

The growing use of the Internet promotes the replacement of traditional manual transactions by equivalent electronic services. Research was carried out to investigate enhanced services related to electronic mail. This paper points out that a certified email protocol has to provide the sender of a certified email with an evidence that this email has been either received or refused by its recipie...

It has been widely accepted that fairness is a critical property for electronic commerce. Fair payment protocol is designed to guarantee fairness in a payment process over asynchronous network. Fairness means that when the protocol terminates, either both parties get their expected items, or neither does. In this paper we first present a new generic offline fair payment protocol with fairness, ...

The EFTWeb is a World Wide Web based system that allows the interaction between users and contents. The users can be students and teachers that place, modify and use available contents. The system provides the means to control security, intellectual property rights (ipr), and billing issues, giving both type of users the necessary tools to access the system, prepare materials and use them. One ...

We attempt to detect the possibility to modify the catalytic property of Pt/graphene using small organic molecule. Results of density functional theory calculations show that ssDNA segment and L-leucine modify the electron transfer at the interface, changing the electronic property and redox property of Pt/graphene catalyst system. L-leucine promotes electron transfer from Pt and increases the ...

The ability to control electronic property of a material by externally applied voltage is greatly anticipated in modern electronics, and graphene provide potential application foreground for this issue on account of its exotic ambipolar transport property. In this study, we proposed that inorganic-graphene intercalated nanosheet is an effective solution to optimize the transport property of gra...

Ca12Al14O33 (C12A7, 12CaO·7Al2O3, or [Ca12Al14O32]:O) is a material with a clathrate cage framework, positively charged and stabilized by anions occluded within 17% of the cages. The occluded anion is modular and can be elemental, polyatomic, and electronic in nature. This review focuses on the electride C12A7 ([Ca24Al28O64] :(4 ∗ ∂)e−(2− ∂)O2−), where O2− anions are replaced with electrons, an...
